  Effects of 17-alkyl-16,17-dihydrogibberellin A5 derivatives on growth and flowering in Lolium temulentum

  摘要：

  Several gibberellins in which the 16-methyl group of the 16-epimers of dihydro-GA(5) had been replaced by ethyl, n-propyl and n-butyl were prepared and tested at doses of 1, 5 or 25&mgr;g per plant for their effects on stem growth and flowering of the grass Lolium temulentum. The ethyl and n-propyl derivatives were most inhibitory of elongation, the exo-isomers being more active than the endo-forms. While both isomers of dihydro-GA(5) promoted flowering, among the 17-alkyl analogues, only the exo-ethyl derivative showed significant activity.
